ABRAHAM MARTIN, OF PARIS, FRANCE.

ELECTROTHERAPEUTIC EXERCISING APPARATUS.

SPECIFICATION forming part of Letters PatentNo. 600,230, dated March 8, 1898. Application le. November 23, 1897. Serial No. 659,548. (No model.) Patented in France May 10, 1897, No. 266,784.

To ctZZ whom it may concern.-

Be it known that I, ABRAHAM MARTIN, of the city of Paris, France, have invented an Electrotherapeutic Exercising Apparatus, (for which I obtained Letters Patent in France on the 10th of May, 1897, under No. 266,784,) of which the following is a full, clear, and exact description.

This invention relates to a system of electromechanical exercising apparatus Whereby, in addition to the muscles being mechanically exercised, all or any part of the human organism is subjected to electrical action proportional to the work developed.

In addition to the uses above mentioned the apparatus may also be employed for reducing obesity.

My apparatus not only permits of producing power, but also of giving to the body a general course of gymnastics by employing the individual strength to set in movement a magneto-electric generator or its equivalent which when in action generates a current which may be caused to pass through the entire organism or certain parts of the body only. Thus if it is desired to electrize the arms it is simply necessary to place the hands upon the contacts on the crank-handle in or- For the abdomen a belt would be employed provided with metallic plates connected with the dynamo. For the legs two bands, also connected to the poles of the generato1,would be applied either on the ankles or at the knees. For the spine a kindof back-support would extend from the nape of the neck to the lower part of the vertebral column, provided with a metallic plate at each end. It will be, however, readily understood that the current may be applied to any other parts of the body than those mentioned, it being simply necessary for this purpose to provide at suitable points contacts connected with the poles of the electric generator. The length of the crank-arm is such that its throw is sufficient, when the apparatus is is use, to compel the body to assume a considerable degree of inclination, which stimulates respiration and circulation and at the same time develops the flexibility of the body.

It will be seen from the foregoing that the apparatus may be thus utilized for performing exercises of strength and movement, while at same Vtime producing an electric action.

My invention is illustrated in the accompanying drawings, in which- Figure l represents a face View, and Fig. 2 a corresponding side View, of the apparatus.

The same letters of reference denote like parts in both figures.

a is the frame of the machine, upon which is mounted a shaft b, carrying a pulley c, by which is driven a magneto-electric generator eZ. One of the poles is connected by a cord e to one of the hand-grips f of crank-handle r, the other pole being connected by the cord g to the other hand-grip f. Upon shaft b is mounted a drum 71., encircled by segments t', about which is wound a cord 7c, one of whose ends is attached to a spring-balance Z and the other end to a pulley m., so as to act as a hand-brake on the drum 71.. A lever n, provided with notohes, each of which represents one kilogram, enables the spring of balance Z to be put in tension for the purpose of in-4 creasing the pressure of the brake upon the drum, and consequently of increasing at will` the resistance ot the exercising movement. A graduated dial-plate o is revolved by a worm on shaft b in relation toapointer p and indicates the number of revolutions of the crankhandle,a gong g being sounded at every ten revolutions.

The counter,in combination with the graduation of the spring-balance, serves to indicate the power which has been developed. For example, if the resistance equals ten kilograms on the spring-balance each revolution of the crank-handle represents ten kilogrammeters, and when the gong sounds after ten revolutions it represents one hundred kilogrammeters.

The pulley c, which drives the magnetoelectric generator d, may be disconnected` from shaft b, so as to allow of the apparatus being used for exercising purposes only.

I claim- 1. A system of electromechanical apparatus for exercising the muscles of the human body and thereby generating an electric action applicable to all or any part of the body, comprising a frame u., shaft b, pulley c ac- IOO tuating a magneto-electric generatord whose poles are respectively connected to the handgrips f of crank-handle 1', a brake-drum h encircled by brake-shoes, segments z' embraced by a cord k connected to a spring-balance Z and also to a regulating-pulley m adjustable by means of a notched lever n to vary the tension of the cord and spring-balan ce substantially as specified.

2. In an electromechanical gymnastic apparatus, the counter comprising a graduatedv dial o operated by a Worm on .shaft b and moving past a pointer p for indicating the number of revolutions of the crank-handle;

and the gong g sounding every ten revolutions.
